My invention relates to wind-up devices and more particularly to wind-up device for winding material into a liner'. i

In a co-pending applicationof Daniel E. Hennessy, Serial No. 25,166, iiled April 22, 1925,is disclosed and claimed a wind-up device for receiving, directly from the cutter, rubberized material which has been partially severed, and winding it into a wide liner roll under conditions to prevent wrinlrling or separation of the partially cut strips and so as to form a tight compact roll. In certain cases it is desirable to provide an opportunity to measure and otherwise inspect the material 1 as it passes from the cutter to the liner roll. At the speed of operation necessary for economical production the length of material eX- posed for inspection must be substantial, andV lit is further essential that the relation of the rubberized material to the liner should remain constant from the time the material meets the liner until it is iirmly wound in the roll. It is the object of my invention to provide a device which will meet all of the requirements and conditions imposed in handling vrubberized material, so out, and at the same time give ample opportunity for inspection. rIhe manner in which I accomplish this together with further and more specific objects of my novel combination of parts will be apparent from the following specification and claims.

In the accompanying drawings which illustrate one embodiment of my invention,

Fig. l is a side elevation of the device;

Fig. 2 is a plan view;

Fig. 3 is a detail on an enlarged scale of the web guiding mechanism, partsbeing shown in section;

ll is a section on line 1 4 of Fig. 3;

Fig. 5 is a diagrammatic view illustrating the function of one of the means for control ling the fabric.

Referring to the drawings, 1 designates a base supporting an upright frame 2 in which are journaled a shaft 3 for the leteoif roll l and a shaft 5 for the talregup roll 6. Shaft 5 is positively driven in thev direction of the arrow in Fig. 1 through a sprocket 8 secured thereto and connected by a sprocket chain 9,

to a sprocket 10 connected in turn by suitable gearing l2 to an electric motor 13 mounted on base 1. Shaft 3 of the let-ott roll is provided with a brake, indicated at 15, to apply tension to the liner 16 as the latter is drawn from the let-olf roll by the positive drive of the take-up roll. From the let-Cif roll the liner passes over a smooth roll 17, beneath a spreader roll 18, over a fined bar 19 and beneath a smooth roll 2O positioned at the forward edge of the frame, rolls 17, 18 and 20 being freely journaled in suitable bearings supported by frame 2.

Adjacent base 1 and in substantial alignment therewith is an inspection table 25. Mounted in suitable journals 26 secured to that end'of the table remote from the letoli and wind-up devices just described is a roll 27 about which the liner passes from roll 20, as shown in Fig. 1, and which is provided with a tension imparting brake 28 (see Fig. l). From roll 26 the liner travels rearwardly over table 25, beneath a roll 29 journaled in bearings 30 extending from the rear edge of the table and beneath a gravity actuated roll 31, the shaft of which slides freely in slots 33 formed inv standards 34C secured to frame 2 of base 1, and thence to wind-up roll 5. The material for which my device is peculiarly adapted is a web of rub berized cord fabric which has been partially cut into transverse strips, that is, in which the upper coating of rubber and the fabric or cord body have been severed and the strips are held in web form by the under coating of rubber. Such a web is indicated at 36 as coming from a vertical bias cutter, not shown. It is difficult to alter the relation of a web of this character with respect to its liner, once the two have been. brought together, without disrupting the uncut coating of rub ber and it is therefore necessary to bring the web into contact with the liner in proper position and alignment. This is especially true where the liner is drawn over a table of substantial length. For this purpose I provide a roll i0 in the form of a shell rotatable on a rod 411. Rod l1 is secured in brackets 13 extending from the edge of the table 25 so as to position roll 40 beyond roll ofthe roll 40. in the planeof the table and the web 36 in passing over the roll may thus be nicely centered with respect to the liner as it comes into contact with the latter. An-

other variable factor to be contended with is a variation in the tackiness of the rubberized sur-face ofthe web which affects its tendency to adhere to they liner and the resultingl tendency tofwrinkle or break at. the

.cuts as., itl accommodates itself .to the liner in being wound in a roll. To take care-of this variable factor the rod 41 isv formedat one .end with a reducedportion 50' upon which tionv 50 is made of sufficient length so that wheel 51 .may be. backed off entirely'free of f rol'l40 to permit the operator toA grasp ,the

endof roll 40 with'hisvv hand and vary the .drag vexerted by roll40 or its position ron f rod 41' bywthey pressure land Aposition of hisy hand. This. procedureis found desirable in cases lwhere variations inthe tackinessv or lalignment of the web. occ-ur with a rapidity which is difficult to follow withhand wheel j 51- and handle` 48.

scribed,v referencebeing had to the diagrammaticFig. 5, in which for convenience of illus- Theroll 31 previouslydescribed performs aspecial'function which willbe now de- :tration the combined liner and web arey desi rateat the-cuts. 4l overcome this. condition by the provision of the; roll 31 which when "the sag occurs assumes. the dotted linel posi- 155' .tion in Fig. and prevents free slack in thev linerl and web. Upon resumption of the operation the roll. resumes its running position, shown in full line, absorbing by. its vweight the tendency .of the liner and web to whi ,As will be clear fromV the above description .the tension inthe relatively long runs `of the .liner aboveand below the table are nicely controlled by brakesand .28, the

web. is` brought into contactwith the liner under nice control by roll and its adjustments and the relation of the web and liner is maintained by roll 31, giving an opportunity to adequately inspect the web as it passes over table 25.

The base1 1. is preferablyl provided with wheels 6010 form a carriage running on rails 61 permitting the carriage to be moved away from table2,5,to. permit. loading. andunloading, and a. second carriage, designated at'62, and exactly vsimilar' to 'that above/described except that it is adapted to run on rails 63 positioned at right angles to rails 6.1, may be vprovided to cut the interruption due to loading and unloading to a minimum.
